Imari Ware plates

I'm assuming these 6 1/8-6 1/4" (15.5cm) plates are modern, however, I see the one with bamboo trees in the middle regularly described as vintage. Or older. Let me put it this way: there's an awful lot of them in this design, in awfully good condition, for items as allegedly old. My 2 have identical backstamps. I'm wondering about pattern names. I've found them both on ebay.com, the one with the 3 daisy or corn flowers called "Empress" in a larger plate (with 4 flowers) named the same on Replacements.com , but I can't put a name to the one with the bamboo trees on the right of the centre. I have seen it backstamped as "Miyako Handpainted Porcelain Imari Ware" with the same kanji, but no pattern name in English.
So - are they even mildly vintage ?
- Does anyone know a pattern name for the bamboo trees one?
- What does the kanji actually say? ?
